Modbus Gateway settings
The serial server will perform conversion from Modbus/TCP to Modbus/RTU, allowing polling by
a Modbus/TCP master. The Modbus IPSerial Gateway carries out translation between Modbus/TCP and
Modbus/RTU. This means that Modbus serial slaves can be directly attached to the unit's serial ports
without any external protocol converters.
